Enhance `validate` command to perform Metaschema and constraint-based validation of modules

User Story

As a developer of Metaschema-based software, in order to find precise modeling errors XML Schema based validations cannot find, I would like the metaschema-cli validate ... to natively used the Metaschema model and constraint-based validation of models.

NOTE: This request came from a consideration during a review of a code cleanup in https://github.com/metaschema-framework/metaschema-java/pull/230#discussion_r1826650576.

Goals

[ ] More precise error detection for Metaschmea models
[ ] More precise, informative error reporting upon detection that is more helpful than XML Schema validation

Dependencies
